Discover more about Cetti Bay

Cetti Bay, nestled on Guam's southwestern coast, is more than just a picturesque bay; it's a journey through time. This historically rich site, listed on the National Register of Historic Places, offers a unique blend of natural beauty and cultural significance. The bay's coastal area has been inhabited by Chamorros for approximately 3,000 years, with latte stones and pottery shards serving as evidence of their ancient presence. The Spanish later recognized the area's strategic importance, creating a road system that connected Hagåtña to the south through Cetti Bay. Today, Cetti Bay is part of Guam's Territorial Seashore Park, a geological delight showcasing the island's volcanic origins. The twin hills below the Cetti Bay Overlook, Attelong Acho (Black Rock), are pillow lava formations from underwater volcanic eruptions. Hiking enthusiasts will find several trails offering breathtaking views of the bay and surrounding landscape. The crystal-clear waters are perfect for snorkeling and swimming, allowing visitors to explore vibrant marine life. One of the most well-known scenic points of Guam is the Cetti Bay Overlook. The overlook provides views of the volcanic rock that comprises most of southern Guam, especially the pillow lava formations of Attelong Acho, or Black Rock, to the north. In the distance looking southward, Cocos Island can be seen. Cetti remains a popular destination for hiking or boating adventurers and others who want to enjoy its beach area.
